Jan 3, 2003Repeatability coefficients of variation (C.V.) ranged from 6.8 to 14.6%. Each analysis included a blank determination of the saliva simulant without the reference sample.
The DEHP migration of six toys exceeded the SCTEE guidance release value of 1.7 microg min(-1) 10 cm(-2). Substitutes found for phthalates plasticizers are acetyltributylcitrate, tributylcitrate

The release of phthalates upon continued agitation, without replacement of the saliva simulant, reaches a plateau in approximately 15 hours. However expressed in the release per minute,
The optimized conditions were 5 extraction cycles with 1600 μL of saliva simulant and desorption with 200 μL of ethyl acetate using 5 cycles with the same aliquot. The
- How are phthalates analyzed in a migration test from PVC toys?
- In this Application Note, the analysis of phthalates in a migration test from PVC toys is performed using the Agilent 1260 Infi nity Analytical SFC System in combination with an Agilent 6130 Single Quadrupole LC/MS.
- Which phthalate is detected in GC-MS?
- At least one PAE was detected in 81% of samples, and di-n-octyl phthalate was found in higher concentration, achieving the migration of almost 30 μg per g of sample.

- What are phthalic acid esters?
- Phthalic acid esters (“phthalates”) are the most commonly used plasticizers in polyvinyl chloride (PVC) based products due to their compatibility and softening capability . The plasticiser content can be up to 50% by weight.
- Can mixed isomer phthalates be analyzed?
- It poses a signifi cant analytical challenge to perform the analysis of these mixed isomer phthalates.
- What are phthalates used for?
- Phthalates form a group of well known plasticizers that are often applied to soften polymers, such as PVC, in toys. High molecular weight phtha- lates are used as polymer additives. Phthalates are not chemically bound to PVC and can leach out or evaporate into the environment.
- How accurate are phthalate ion abundance ratios?
- Replicate measurements (n=15) on the ion abundance ratios for each phthalate was determined to calculate the precision of the calibration, and the relative standard deviations of the qualifier to the quantifying ion. The relative standard deviations on the relative abundances did not exceed 10% for all the phthalates tested.
